About the Kilometer/Hour to Foot/Second conversion
The conversion factor from Kilometer/Hour (km/h) to Foot/Second (ft/s) is 0.91134, meaning 1 km/h = 0.91134 ft/s and inversely 1 ft/s = 1.09728 km/h. That makes the Foot/Second the larger of the two units in the speed category, where the SI base unit is the meter-per-second. Every ratio here is derived from the SI/international definition rather than a rounded approximation, so results are stable across repeated conversions.
